To (tut/I10!!! it may comic/7.21

Be it known that l, (lnoncr. \V. BEADLE, a citizen of the lnitcd States. residing at lla vonne. in the countw of Hudson and State of New Jersey. have invented certain new and useful improvements in Machines for Ivlaking Iaper (.ups; and I do herelrv declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for the manufacture of paperdrinking cups, and has for its object to provide an eliicient, simple, compact, and comparatively inexpensive machine that may be placed at public drinking places, and of such a character that it maybeoperated by hand for manufacturing and dispensing individual paper drinking cups capable of holding liquids for sufficiently long intervals of time to serve the patrons.

To these ends the invention consists in the novel detailsot' construction and combinations of parts more fully hereinafter described and particularly pointed out in the claims, and comprising a means for convolutely winding on a collapsible mandrel a. thin sheet ol parallined paper, and then forming a cup with a concave reinforced bottom, in such a manner that the cup will be liquid tight. and may rest in an upright position when placed on a table or other support.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views :-Figure 1 is a front perspective view of a machine made in accordance with my invention; Fig. 2 is a detail view of a drinking cup made on my machine, a part being broken away for the sake of clearness; Fig. i is an end elcvational view of my machine, looking toward the left, as seen in Fig. 1, with the end plate removed; Fig. 4 is an end elevational view looking toward the right, as seen in Fig. l. with the end plate removed: Fig/5 is a rear elevational view, the casing being shown in section; Fig. 13 is a top plan view of the machine with the top plate removed; Fig. 7 is a horizontal sectional view taken on the line 7-7 of Fig. 3 and looking down; Fig. 8 is a detail view of the mandrel, bottom forming die, and their operating parts; Fig. 9 is a side elevational view of the parts shown in Specification of Letters Patent.

Sheet 7. is a view showing the crimping punch in position to compress the paper between it and the crin'iping die to complete the formation of the bottom of a cup.

This machine, on which the cups may be manufactured by the patrons while placed at a public drinking place, is composed of the base plate 1. back plate '2. side plates 3 and l. and front cover 5, all of which are sccurcly connected together to form a casing adapted to be held to a wall or other support by the bolts (3.

During the operation of making a drink- 'ing cup, a paper feeding mechanism, a cutting mechanism, a winding mechanism, a bottom forming mechanism, and anejectmg mechanism are properly timed and brought a crank 12 for operating the machine when desired.

A gear 13 is also mounted on the stud shaft 10. and meshes with a pinion 14 mounted on the mandrel shaft 15, mounted in an extended bearing 16. carried by the plate 3. The shaft 15 carries on its inner end a mandrel 17, Figs. 5, 8, 9, and 22, and on its outer end, a sprocket 18, over which is adapted to travel a chain 19 for transmitting power to the sprocket- 20 held on the outer end of a shaft 21 carrying the paper feed roll Fig. 4. The-said shaft 21 is supported atits inner end by a bearing 23 mounted on the bracket 21 held to the back plate 2. and at its outer end in a bearing 25, mounted on the side plate 3, Figs. 4, 5 and (i. Mounted between the end plate 3 and the bracket 2-1 in suitablcbearings, is a paper roll shaft 26 for supporting a roll of paper 27,.Figs. 3 and 6.

28. indicates a shaft also mounted between the end plate 3 and the bracket 24 for sup- .porting a movable yoke. 29 which carries a contact paper feed roll 30. This yoke is provided at its lower end with a rcarwardly extending arm 31, Figs. 4, 5 and 18, which is adapted to contact with and be operated by a cam 32. mounted on the cam shaft 7 for causing the roll 30 to contact with the feed roll for forcibly feeding the paper from the roll 27 to the mandrel 17 at the proper intervals. A sprin 33 connected at one end to the yoke :29 and at the other end to the paper roll shaft 26 returns the yoke to carry the contact roll 30 to its inoperative position.

After a sufficient length of paper has been fed by the feed rolls, to form the cup with a plurality of convolntions, and to allow the ends to overlap as shown in Fig. 28, the cutting mechanism is brought into operation for. severing the paper into proper lengths for the mandrels. This cutting mechanism comprises a stationary shear member 34, 13 and 14-, rigidly held at one end by a screw 35, to the end plate 3, and at the other end by a screw 36 to the bracket 24 and a movable shear member 37 pivotally mounted at 38 to the bracket 39 held to the end plate The outer or free end of the movable shear 37 is held in an open position by the spring 40, secured by the screw 36, and contacting with the pin 11, carried by said shear 37. Said free end is also sup- 'of contact between the ported by a bracket 42 rigidly secured by a screw 43 to the under side of the stationary shear 34.

A movable hammer bar 44 pivotally mounted at 45 to the bracket 39 carries on its outer end a hammer head -16 on the outer side of which is pivotally mounted, as at 47, a trip finger 18. This trip finger carries on its inner side a pin 49, which is adapted to travel within the recess 50, Fig. 17, on the under side of the hammer head l6, and to contact with the adjusting screw 51, also held in the hammer head -16. A spring 52 adapted to always hold the pin 49 in contact with the adjusting screw 51.

Pivotally mounted on the shaft 21 and adapted to contact with the trip finger 48 is a pawl 53, the arm 5% of which is pivotally connected as at 5-" to the upper end of an operating rod 56. The lower end of this operating rod slides and is guided on the cam shaft 7 by its slot 57 when the pin 58 carried by said lower end, contacts with the cam 59 mounted on the said cam shaft 7.

When the pawl 53 is operated by the cam 59 through the said operating rod 56, it causes the movable hammer bar 14 carrying the hammer head 40 to so move as to tension the spring 60 until the end of the pawl 53 passes the end of the trip finger -18, whereupon the hammer head is released, and under tension of the said spring 60, is caused to strike the movable shear 37 and to sever the paper, which has been previously fed between said shears 84: and 37, see Fig. After the cam 59 has passed the pin 58, the operating rod .36 is moved longitudinally of its slot 57 and returned to its initial position by the action of the spring 61, the ends of which are connected to the said operating rod 56 and the stationary bar 34, as shown. The pawl 53 in returning to its normal position-swings on the shaft 21 as a pivot, and passes the trip finger 48, putting under tension the spring 52, which immediately returns said finger =18 to its normal position.

Through the adjusting screw 51 the point trip finger "l8 and the pawl 58, can be accurately adjusted thereby regulating the exact time of tripping, and therefore. the length of the paper to be severed. After a proper length of paper has been provided by the cutting mechanism just described. it is wound on the mandrel 11' by the mechanism now to be disclosed.

The inner end of the mandrel shaft 15, on which the mandrel 17 is mounted, is provided with an enlargement 63 Fig. 22, and said enlargement carries on one end a collar (v-t. while on the other end. there is formcd'a cone 6:"). Slidably mounted on the enlargement G3 is a sleeve 66 which is provided with a circular groove 67 and a recess 68. i

' spring 73 surround n the inner flan es Ti ot' the collapsible segments 69, keep the segments in contact with the cone (35. The collapsible segments are held against rotation on the cone (if) by the pins 75, Fig. 23, which are carried by the sleeve (ll). working in the slots 76, out in the extended flanged portions of said segments.

ii concave crimping die 77 provided With a series of corrugations 7S terminating in a central cone 79 is held by pins 80 to the outer ends of the collapsible segments (39.

A mandrel sleeve 81 provided with a flange is held by the screws 83, l igfll, to a plate 8t which plate is suspended from a carriage 85 provided in the bearings 86. This carriage carrying the mandrel sleeve Pd. is adapted to travel on the guide rods 87 held in the side plates 3 and 4 oi the machine. lhe sleeve 81 is adapted to surround the mandrel and crimping die when in the winding position Fig. '22, and is provi ded with a slot 8 Fig. 21. through which the. paper is guided to the mandrel 1-7 from the paper guides 8 mounted on the plate 8i.

Contact roller 90, 91, and 92 held on the mandrel sleeve 81 by the springs 93 are adapted to contact through the slots 88, i l and 95 with the collapsed segments of the mandrel l7 when'they are in an expanded position. see dotted lines Fig. 24., and guide the paper 200 within the mandrel sleeve around the mandrel when Winding the tube. '1 he tension on the s n-lugs 93 for regulating the pressure of the contact rollers 91 and 92 may be regulated by the adjusting screws 96.

Spring pressed pins 97, Fig. 22, mounted in recesses 08, within the plate 84, are adapted to project a. slight distance within the mandrel sleeve for engaging. the end oi. the linished cup and sliding it oil of the mandrel when the ejecting mechanism-is brought into operatim'i, as will be hereinafter described.

'lhe segments (3!) ol the mandrelare held in the expanded position during the complete cycle o'l making a cup, by the action of a cam 99. mounted on the cam shaft 7, Fi -s. 25? and 26. operating; the cam lever 100. Tlhrs cam lever is pivotally mounted as at 101.cn a bracket 102, held to the upright bracket 103, Figs. 5 and 7, for Working in theciricular groove67 'o-lt'the slidable sleeve (16. Figs. 5. 7 and 22. and causes the cam 0: to force outwm-dly the segments 69, as "ll be readily understood. The paper is of suliieient width to extend beyond the end of the mandrel segments, Figs. 16 and St, so that the end ot the formed tube may be overlapped to form the bottom of the cup, as shown in Fig.

do far as has now been disclosed, it will be clear if the lever 12 is turned, the shaft 10 will cause the pinion 9 to turn the gear a. and the gear .13 to turn the pinion 14, sprocket l8, sprocket chain 19, sprocket 20, shaft 91., and paper feed roll 22, carried by said shat't. Further. the turning of the gear 8 will cause the. shaft 7 to revolve, which carries the cam 31:, adapted to contact with the extension 31 on the yoke 29. The action ol. the cam 32 Will therefore cause the said roll 0 to periodically carry the paper 200 into contact-with the feed roll and thereupon permit said feed roll to force said paper downwardly through the guides 89. Located immediately above said guides, however, are the shears 3d and 37. and the parts are so timed that the latter aut-oniaticallv cut said paper into proper lengths for forming a tube 201 on the mandrel 1? located immediately below said guides 89. That is to say, the paper 200 is fed by said guides. Fig. 24, to a point be tween the roller 00 and the said mandrel when. in its expanded condition, after the shears 2-H and 37 have been operated tlirough the medium of the rod 56 and hammer 4 1, the said rod being itself operated by means oi the cam 57, carried by the rotating shaft 7. ml after said paper reaches said roller 90, the mandrel being rotated through the medium of the pinion 14 and shaft 15, the said paper 5.200 is passed by said mandrel successively under the rollers 92 and 91, and therei'lpon convolutely wound into a tube. The said paper. however, is chosen of a width to extent beyond the free end of said mandrel a distance sullicient to permit a bottom to he .t'ormed on said tube out of said extruding paper by the mechanism now to he deserihml. A bottom 'lolding lever 104-. l igs. I. T and 15, yn'ovidcd at its upper end with an opening i l-i is pivotnlly mounted at to a. bracket 107 held to the base. plate I.

A cam 108 mounted on the cam shaft 7 contacts with a pin 10 held on the side of the bottom folding lever and as the mandrel revolves, forces it into contact with that part of the paper that extends beyond the end of said mandrel, thereby folding it inward over the crim 'iing die of said mandrel, as illustrated in Figs. 15 and 16. and thereby partially forming said bottom. After the said cam 108 has passed the pin 109, a spring 110, Figs. at and 15, held at one end to the upper end of the bottom folding lever &

folding the end of the paper over the end of the mandrel and die, Fig. 34, Sheet 8, the crimping punch 111, Fig. 8, mounted on the shaft 112, slidably held in the side plate 4 and in the bearings 113 on the bracket 114 is brought into operation to complete the formation of the bottom of the tube or cup by the mechanism that will now be described. The face of this crimping punch 111 is of convex form, as shown, and is provided with a series of corrugations 115 terminating in an inverted cone 116, which are complementary to like parts 1 on the die 77.

Rigidly connected to the shaft 112, is a block 117, Figs. 4, 6, 7, 8 and 19, to the underside of which is pivotally connected one end of a toggle lever 118 the other end of which is connected to a cam following member or block-119. A second toggle lever '120 is also connected at one end to the cam following block 119 and at its other end to a bracket 1.21, held to the side plate 4 of the machine. 5

a A cam;122 mounted on the cam shaft 7 is adapted to actuate the said block 119 and through the toggle levers 118 and 120 force the crimping punch 111 from its position of rest, as shown in Figs. Sand 7, in to its crimping position, as shown in Figs. 8, 9

' and 31, thereby compressing the paper hetween it'and the crimping die 77 and completing the formation of a bottom for the paper cup of a concave corrugated shape, as shown in Fig. 2.

A light spring 123, Fig. 7, which has one end connected to the cam following block 119, and the other end to a rod 124, held in the side plate 4, is adapted to hold the face of the block in proper relation to the face of the cam 122, as will be clear from the drawings. The cup A after being completed on the mandrel, is ejected by the mechanism now to be described. The bracket 114,

' Figs. 5, 6, 7 and 10, mounted on the base plate-1 is provided with the side plates 125 and 126-in which is journaled in bearings 127 a shaft 128.

Mounted on the shaft 128, on the inside of the plates 125 and 126 are two intermittent gears 129 and 130, Figs. 10 and 11, which are adapted to actuate racks 131 and 132 provided with the rest portions 133 and 134.. These racks are held above the gears 129' and 130 to the. upper portions of the side plates 125 and126 by the guide stays 135, the rack 131 being of greater length than the rack 132 and connected to the carriage 85, Figs. 6, 7, 8 and 11, for sliding the latter along the guide bars .87 when removing the cup from the mandrel as will be hereinafter described.

The rack 132 is provided with a rearward extending portion 136, having a slot 137 in which is adapted to travel a pin 138 held in the end of a rod 139, the other end of adapted to mesh with a gear 142 held on a stud 143 mounted in the side plate 126.

144 indicates a link pivotally connected at 145 to the gear 142 and at 146 to one end of a cam lever 147. This cam lever 147 is supported on its other end by a stud 148 held to the base plate 1, and carries a cam pin 149 which travels in a cam groove 150 cut in the earn 151 mounted on the cam shaft 7.

Immediately after the cam 122 has caused the crimping punch 111 to move forward and perform its function, the cam 99 through the medium of the lever 100 and slot 67 collapses the mandrel 17, Fig. 22, by forcing the cone 65 toward the left, as seen in said figure. and immediately following thcse movements the cam 151 through the cam lever 147 actuates the link 144 which through the gears 142, 141 and intermittent gears 129 and 130 move the racks 131 and 132 rearwardly, as shown in dotted lines in Fig.8.

The rack 131 with the carriage 85, plate 84, mandrel sleeve 81 connected thereto and pins 97, removes the finished cup A. from the collapsed mandrel and carries it within the said sleeve from the position shown in Fig. 31 to that shown in Fig. 32. The rack 132 moving in unison with the rack 131 causes the crimping punch 111, by means of the rod 139 to also move backward with said sleeve, as indicated by dotted lines, Figs. 8 and 9. The backward movement of the punch is stopped, however, by the rest portion 134 on the rack 132 engaging with the rest portion on the gear 130. But, the movement of the shaft 128, carrying the gear 129 causes the rack 131 to further continue its backward movement to the ejecting position, wherein the sleeve is forced over the now stationary punch and the cup forced out, as shown in Fig. and indicated in dotted lines in Figs. 8 and 9. The rest portion 133 on the rack 131 now engages with the rest portion of the gear 129 and said rack hecomes stationary. But, the continued rotation of the ram 151, reverses the movements of the racks 131 and 132, through the cam lever 147, the link 144, gears 142, 141, and

' shown in Fig.

end 161, which is adapted to coiip'erate with,

the action of the crimping punch pushing it out of the mandrel sleeve, as disclosed.

above, it falls down into the chute 152 and-is delivered through the opening 158 in the casing 5 to the receiving tray 154.

A push'button 155 mounted in the side plate 8, Figs. '1, 3, 5, 6, 7, 25 and2'8, is provid'ed forreleasing the mechanism to start the machine. This button is pivotally connected as at 156 to a trigger15'7 pivotally mounted at 158 to a block 1 59 held by the screws 160 to the inner face of side plate 3. The trigger. 157, preferably of the shape 26, is provided with an upper :1 lug 162, secured by the screws 163 to the cam 99, and to thereby hold the mechanism in '21 locked position.

A spring 164, held by the screws 165 to the inner face of side plate 3, is provided with a raised portion 166 which is adapted to cooperate with the notches 16? and. 168

in the lower end of the trigger 157 undhold the some in either the locked or unlocked position.

When the push button is pushed in to start the machine, the raised portion 166 on the spring 164 engages in the notch 168 on the lower end of the trigger and holds the same in an unlocked position, as shown by dot-ted lines in Fig. 26. This movement of the push button also releases the upper end 161 of the trigger from engagement with the lug 162, and allows the crank shaft 7 to be operated by the crank 12, ashes been previously disclosed.

During the early rotation of the cam 99. the lug 162 contacts with the lower part of the trigger, should it be in the path of said log; and returns the same to its locking position, whereupon said trigger is again held in said locking position by the raised portion 166 on the said spring 164 engaging with'the notch 168. rying the lug 162 has made one complete turn, the lug 162 will in all cases, again contact with the upper end of the trigger, and lock the machine. The locking tr1gger 157 thus prevents the crank 12" "from being turned in one direction when the button is not pressed, and a spring stop 169 having one end held by the screws 170 to the back plate 2 and its other end 171 contacting with the gear 8, Figs. 3 and 25, prevents the crank from being turned in the other direction: 1 11- 1291* above set forth.

'lherefore, after the- Cain 99 car A friction roller 172, Figs. 8,4, 5 and 6, supported by rods 1T3 pivotally mounted at 174 to the back plate 2i's adapted to contact withthe paper roll 27 and prevent anyslack in the paper between said roll and the feed rolls and 80-. end to other end to the paper roll shaft 26, serve to hold the friction roller 172 in close contact with the paper roll 27. t

The operation of the machine is as follower- A person desiring to secure a cup, first pushes in on the push button 155 and trips the trigger to the dotted position shown in Fig. 26. This movement disengages the upper end 161 of said trigger from the lug 162 mounted on the cam 99, and leaves the crank 12 free to turn. The crank 110W being turned to the left, transmits motion to the crank shaft through the pinion 9 meshing with the gear 8. Through the gear- 13 meshing with the pinion 14, mounted on the mandrel shaft, the mend-rel is revolved, and throught'he sprocket 18 mounted on the end' of the mandrel shaft, chain 19, and sprocket 20, mounted on the" shaft '21, the driving paper feed roll is revolved, all as The cont-act feed roll is next brought into contact with the driving feed roll by the action of cam 32, and after a proper length of paper has been fed, it is then severed by the cutting mechanism which is actuated by the cam 59. The severed paper is then wound on the mandrel Within "the mandrel sleeve, while a part of the Wound paper extends beyond the ends of i acting Withthe cam 99, all as has been like wise explained above. The bottom folding lever 1041- is next brought'into operation by the action of the cam 108' and that part of the paper which extends beyond the end of the mandrehend sleeve is folded over the mandrel end and die carried thereby in a neat and compact manner. While this movement is taking place, the own 122, is through the toggle levers and shaft 112, slowly advancing the crimping punch. l1nmediately after the bottom folding lever has returned to its initial position, the cum 122 forces the crimping punch into the crimping position, thereby compressing the paper between it and the rapidly revolving crimping die, mounted on This completes the formation of a paper cup with n concave corrugated bottom. Immediately'following the formation of the bottom of the cup, the action ofthe cam lever 100, coacting With'the cam 99, and the com 151 actuates the mandrel is collapsed by 12o the end of the mandrel.
